I'm having an issue on my LIVE forum, as well as, the new Test Install forum. I cannot edit any options in the Guest Group. The groups: Admin, Members and Moderator works fine.

Screenshot of the error, and how to do a possible fix for this.  Thanks.

Edited to update the version: This is with v4.7.15

Disable strict mode on your mySQL instance.

Hmmm - actually, this looks like it could be reproducible without strict mode involved...

Ignore that - it's only reproducible with strict mode enabled on mySQL

For the guest group, the g_mod_post_unit evaluates to NULL in applications\core\extensions\core\GroupForm\Content.php because it's not present on the form:

if( $group->g_id != \IPS\Settings::i()->guest_group ){
	$form->add( new \IPS\Helpers\Form\Custom( 'g_mod_post_unit'......

...but the Save function doesn't take that into account:

/* Mod Queue */
$group->g_mod_post_unit = isset( $values['g_mod_post_unit'][2] ) ? 0 : $values['g_mod_post_unit'][0];

Not an issue if not using strict mode.

I cant replicate on my end at all. Please could you let me know exactly what it is you are changing?

The error is thrown only when editing the GUEST GROUP with MYSQL STRICT MODE enabled.

Thanks for the confirmation. I have added a bug report for that.

Just to answer this - nothing is being changed; just saving the group with strict mode on will trigger the error.

Got there now once you mentioned it is still while on strict. I wasnt 🙂 Its not "strictly" (pun intended lol) to do with that. Its an incorrect null value being passed, but thats for the devs to sort

Thanks. Disabled strict mode and I was able to make the changes needed.

I'm having this problem too when trying to change guests permissions on which forums they can view

Yes, this is an open bug report at present

This has now been resolved in the 4.7.16 release. Please update if you are seeing this issue. If you are then still seeing the issue, please let us know.
